HORSE-POWER.

SPECIFICATION forming part of Letters Patent No. 247,354, dated September 20, 1881.

Application filed July 14,1881. (Nomodel) Toall whom it may concern Be it known that I, JOHN T. HOWE, of Am ericus, in the county of Sumter and in the State of Georgia, have invented certain new and useful Improvements in Horse-Powers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

This invention relates to certain improvements in mechanism or apparatus for applying horse-power to machinery; and it has for its objects to provide suitable means whereby the power may be imparted from the driver to the driven shaft with the least possiblefriction, and to provide for regulating and adjusting, relatively, the driving and driven mechanism, as more fully hereinafter set forth. These ob- 2o jects I attain by the apparatus and mechanism illustrated in the accompanying drawings, in which Figure 1 represents an end elevation of my apparatus; Fig. 2, "a side elevation thereof, and Fig. 3, a horizontal sectional view on the line a; no of Fig. 2.

The letter A indicates two vertical frames, which support a portion of the workin g parts of the apparatus.

The letter B indicatesa horizontal shal'tjournaled in bearings O in the lower parts of the frames. The said bearings are formed by the movable transverse bars 0, which are recessed at their ends and are located in the respective frames, the recesses fitting upon the vertical rabbets D thereon in such manner that the cross-bars may move up and down thereon. The said shaft carries a cog-wheel, E, and pinion F, the cog-wheel gearing with a pinion, Gr, on a horizontal shaft, H, which is journaled in bearings formed by the horizontal transverse bars I, which are recessed at their ends, as indicated by the letter K, the said recesses fitting and being adapted to move upon the vertical rabbets D, before mentioned.

The letter L indicates four vertical screws, which pass through the screw-nuts M, on opposite sides of the transverse bars 0 and I. The said screws are provided with squared heads N, by means of which they may be turned by a suitable wrench or key, so as to adjust the shafts carrying the cog-wheels and pinion relatively to each other.

The upper horizontal shaft has mounted upon it a driving-wheel, P, which may be connected by means of a suitable band with a a pulley on a cotton-gin or other machine to which the power is to be imparted.

The letter R indicates a horizontal beveledgear wheel, the shaft of which is journaled in a bearing, S, in the base of the apparatus and projects downward to be connected with a suitable lever, to which the horse or other draftanimal is attached. lhe said wheel intermeshes with the beveled pinion on the lower horizontal shaft in such manner as to rotate the same and the connecting train of gearing when it is rotated. The upper end of the shaft of the wheel It is journaled in a bearing, T, in the bridge U, secured to the base of the apparatus.

In practice the base of the apparatus is secured to the first floor of a gin-house having a cellar or apartment below, the drivingshaft projecting downward therein in such manner that the draft-animal may be hitched to the lever and operate the machinery by traveling around a circle in the usual manner. By means of'the adjustable bearings the parts may be adjusted for wear whenever required.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In combination with the vertical rabbeted frames A,the transverse bars 0' and I, and the wheels E I mounted on shafts journaled in hearings in said bars, the stationary vertical adjusting-screws L and nuts M, whereby the wheels may be adjusted, and the horizontal beveled wheel It, intermeshing with the pinion F and mounted on a shaft provided with a suitable lever, substantially as specified.

2. In a horse-power, the vertical frame A, provided with ways D, in combination with the stationary screw-threaded bars L, sliding journal-boxes, adapted to be adjustable at different heights thereon, and the binding-nuts M for securing the same, as and for the purposes set forth.

In testimony whereof I affix my signature, in presence of two witnesses, this 28th day of June, 1881.

JOHN T. HOWE.
